Rare gas lasers utilise noble gases such as argon, xenon and krypton to generate coherent light through the excitation of metastable atomic states. Unlike conventional semiconductor or solid-state ...
Scientists have developed the first electrically pumped continuous-wave semiconductor laser composed exclusively of elements from the fourth group of the periodic table—the "silicon group." The rapid ...
Stuttgart, Jülich, Leibniz, and CEA-LETI group create laser solely from Group IV elements. New laser created solely from Group IV elements. Built from stacked ultrathin layers of silicon germanium-tin ...
